No, the green checkmarks indicate that the content of the page has changed since your last visit. You can control this globally by going to the Bookmarks tab of the OmniWeb preferences and selecting the appropriate value for "Check bookmarked pages for changes" ("Never" sounds like what you want). You can also do it on a bookmark-by-bookmark basis by bringing up the bookmarks page, selecting a bookmark, and using the Info panel to make the change. Besides the green checkmarks to indicate changed content, there's also a command to show you the next page with changed content: Bookmarks->Open Next Changed Bookmark (cmd-option-C)
